Okay, how stupid do you have to be? Honestly, who thinks that in the US today, they can get away with a “White Only” sign restricting access to a supposedly public place? And the whole purpose was to discriminate against one girl, because the landlord for the pool claimed she used hair chemicals that would make the pool cloudy.

How do you know she uses any chemicals in her hair, let alone what chemicals? Find another way to deal, like requesting the people wear swimming caps. But don’t expect to be able to blatantly discriminate and be given a pass.
